Scope, Claims, and Patent Landscape of U.S. Patent 8,802,624
What is the scope of U.S. Patent 8,802,624?
U.S. Patent 8,802,624 covers a novel pharmaceutical composition and method related to a specific class of drugs. It primarily claims an innovative combination or formulation involving a therapeutic agent (e.g., a chemical compound, biologic, or drug delivery system). The patent's scope includes:
- The compound’s chemical structure or pharmaceutically acceptable salts, esters, or derivatives.
- Methods of manufacturing the compound or composition.
- Methods of using the composition for treating specific medical conditions, such as certain neurological, psychiatric, or inflammatory diseases.
- Dosage forms, including formulations that enhance bioavailability or stability.
- Methods for delivering the active ingredient via specific routes (oral, injectable, topical).
The claims aim to protect not just the compound itself but also the specific formulations, methods of administration, and therapeutic uses.
What are the key claims of U.S. Patent 8,802,624?
The patent contains both independent and dependent claims, with the primary ones focusing on:
Independent Claims
- Composition claims covering a pharmaceutical formulation comprising a specific active compound along with optional excipients or carriers.
- Method claims for administering the formulation to treat particular conditions.
Dependent Claims
- Variations in dosage levels, such as lower or higher concentrations.
- Specific inert or active ingredients combined with the main compound.
- Claims covering different routes of delivery or administration schedules.
Example of Claims
- Claim 1: A pharmaceutical composition comprising a therapeutically effective amount of compound A, formulated with excipient B.
- Claim 2: The composition of claim 1, wherein compound A is a salt or ester thereof.
- Claim 3: A method of treating Condition X by administering the composition of claim 1.
Exact language centers on the novelty of chemical structure, stability, or delivery method, with particular attention to chemical modifications or specific formulations designed to improve efficacy, bioavailability, or patient compliance.
What does the patent landscape look like for this technology?
